Ingredients
  

Main Ingredients
  • 2 lbs Yukon Gold or Russet potatoes These varieties provide a creamy texture and rich flavor.
  • 2 tablespoons olive oil Adds a healthy fat and slight fruitiness.
  • 2 large yellow onions, thinly sliced These are the stars of the dish, turning sweet and golden when caramelized.
  • 4 tablespoons butter For that rich, buttery taste we all love in mashed potatoes.
  • 1/2 cup heavy cream, warmed Adds creaminess for a luxurious mouthfeel.
  • 1 1/2 teaspoons salt, divided Enhances the flavors throughout.
  • 1/2 teaspoon black pepper Provides a subtle kick.
  • 2 tablespoons chopped fresh chives, optional For a burst of color and fresh flavor.

Method
 

Preparation
  1. Peel and chop the potatoes into even chunks and place them in a pot, covering with cold water and adding 1 teaspoon of salt.
Cooking
  1. Bring to a boil, then simmer until fork-tender, about 15–20 minutes.
  2. While the potatoes cook, heat olive oil in a pan over medium-low heat, adding the sliced onions along with a pinch of salt.
  3. Cook the onions for 25–30 minutes, stirring occasionally until caramelized and golden brown.
  4. Drain the potatoes and return them to the hot pot to remove any excess moisture.
  5. Mash the potatoes until smooth using a masher or ricer.
  6. Stir in the butter and warmed heavy cream until creamy.
  7. Season with the remaining salt and pepper.
  8. Fold in most of the caramelized onions, reserving some for topping.
  9. Transfer to a serving bowl, topping with reserved onions and chives. Serve warm.

Notes

To achieve the perfect caramelized onions, be patient and don’t rush the cooking process. For variations, try substituting part of the potatoes with cauliflower or mix in your favorite herbs.
